SRNE SAA 3-in-1 MPPT: The All-In-One Power Solution for Campervans, Off-Grid, and Mobile Systems

When building a reliable off-grid or camper van electrical system, simplicity, efficiency, and safety matter more than ever. That’s exactly where the SRNE SAA Series 3-in-1 MPPT stands out — a compact powerhouse combining Solar MPPT, DC-DC charger, and Smart Battery Charger in one intelligent unit.

Whether you’re travelling full-time, touring Europe on weekends, or building a professional camper conversion, the SAA Series delivers the easy wiring, high efficiency, and robust performance that modern lithium systems demand.

What Is the SRNE SAA 3-in-1 MPPT?

The SRNE SAA Series is a multi-functional charging controller designed to simplify your whole electrical setup by combining three devices into one:

1. High-Efficiency MPPT Solar Charge Controller

Tracks the maximum power point in real time

Up to 99% MPPT tracking efficiency

Harvests more energy than traditional PWM or basic MPPT controllers

Perfect for fixed or portable solar panels on campervans, motorhomes, boats, and off-grid cabins

2. Intelligent DC-DC Charger (Split-Charge System)

Charges your leisure battery from the vehicle alternator

Stable output even on Euro 5/6 smart alternators

Adjustable lithium, AGM, and gel profiles

Ensures safe, fast charging while driving

3. Smart AC Battery Charger

Ideal when plugged into campsite mains or generator power

Automatically adjusts charging stages based on battery type

Works seamlessly with lithium (LFP), AGM, Gel, Flooded, and calcium
